rdocs: Simple Quarto documentation for R packages

Allows to create quarto markdown documentation (.qmd) from /// and ### tokens in text files. Documentation can be created, for example, from .R, .rs and .cpp files.
The package will search for these tokens in the files and generate a quarto website.

This library’s documentation was created using rdocs.

Instalation

Install Quarto and add it to PATH.

Install the package from github: remotes::install_github("daniellga/rdocs", subdir = "rdocs")

or from R-universe: install.packages('rdocs', repos = 'https://daniellga.r-universe.dev')

Usage

An example is showed below, where 2 distinct functions will be documented on the same section, named HFft. It generates a quarto website from lines starting with ### or /// that are right above function declarations.
The website folder is created in the current working directory.
The first line of the block is important, since the name of the variable will be used to group functions into the same one-worded section. This is useful, for example, when working using an OOP approach. For now, to avoid any bugs, it is important that all grouped functions are on the same file.
The user is free to create its headings, line breaks and make use of all other markdown utilities.
All R code identified by r code markdown blocks will be evaluated in a separate R session. If you don’t want a certain part of the code to be run, it will be needed to comment it or avoid the code block representation. If you don’t want to evaluate the code at all, use run_examples = FALSE, which is the default.

/// HFft
/// ## fft
///
/// `fft() -> HArray`
///
/// Computes the fast fourier transform of the `HArray`.
///
/// #### Returns
///
/// An `HArray`.
///
/// #### Examples
///
/// ```r
/// arr = array(c(1,2,3,4,5,6,7,8,9,10,11,12), c(3,4))
/// dtype = HDataType$float32
/// HArray$new_from_values(arr, dtype)
/// HFft$fft(harray)
/// ```
///
fn fft(harray: &HArray) -> HArray {
    HArray(harray.0.fft())
}

/// HFft
/// ## fft_mut
///
/// `fft_mut()`
///
/// Computes the fast fourier transform of the `HArray`.
/// The operation is done in-place.
///
/// #### Examples
///
/// ```r
/// arr = array(c(1,2,3,4,5,6,7,8,9,10,11,12), c(3,4))
/// dtype = HDataType$float32
/// HArray$new_from_values(arr, dtype)
/// HFft$fft_mut(harray)
/// ```
///
fn fft_mut(harray: &mut HArray) {
    let inner_mut = harray.get_inner_mut();
    inner_mut.fft_mut()
}

rdocs::generate_docs("./testscript.rs")

The website will be generated on the current working directory.
